    1 SPACEWARDUINO Kaivan Wadia (Department of EECS) – Massachusetts Institute of Technology Advisor: Prof. Philip Tan ABSTRACT Spacewar! was one of the first ever computer games developed in the early 1960s. Steve Russell, Martin Graetz and Wayne Witaenem of the fictitious "Hingham Institute" conceived of the game in 1961, with the intent of implementing it on a DEC PDP-1 computer at MIT. Alan Kotok obtained some sine and cosine routines from DEC following which Steve Russell started coding and the first version was produced by February 1962. Spacewar! was the first computer game written at MIT. In the duration of this project we hope to implement the same game on an Arduino Microcontroller with a Gameduino shield while examining the original assembly code and staying as true to the original version of the game as possible. 2 TABLE OF CONTENTS 1.

INTRODUCTION The major aim of this project is to replicate the first computer game written at MIT, Spacewar!. In the process we aim to learn a lot about the way video games were written for the machines in the pioneering days of computing. Spacewar! is game of space combat created for the DEC PDP-1 by hackers at MIT, including Steve Russell, Martin Graetz, Wayne Witaenem, Alan Kotok, Dan Edwards, and Peter Samson. The game can be played on a Java emulator at http://spacewar.oversigma.com/.

  • The Real Inventors of Arcade Videogames Copy
    1. The “real” Inventors of Arcade Videogames? As more and more of the early history of videogames comes to light, perceptions of who did what and when keep changing. For example: In a recent paper written by Professor Henry Lowood (Curator for History of Science & Technology Collections; Germanic Collections; Film & Media Collections, Stanford University) entitled “Meditations about Pong from different perspectives”, he reminds us of the story of the summer project of a “recently” (1970) graduated SAIL (Stanford University) student, Bill Pitts, and his friend, Hugh Tuck, as follows: “ The Galaxy Game was a coin-operated computer game for the newly released PDP 11/20, DEC's first 16-bit computer. DEC had fit the PDP 11 into a relatively small box and listed it for a mere $20,000, hoping thereby to open "new markets and new applications." Pitts and Tuck formed a company called Computer Recreations, bought the low-end version of the PDP-11 for only $13,000 and converted the PDP-10 version Spacewar! for this machine, including a Hewlett-Packard vector display, wooden cabinet, and other parts, their expenses came to roughly $20,000. In September 1971, they installed it in Stanford’s student union, where a later version that supported up to four monitors (eight players) could be found until 1979. The Galaxy Game was faithful not only to Spacewar!, but also to the player community (university students and computer engineers) and technical configuration (software code, vector displays, timesharing, etc.) that produced it” Is this not still another story describing the invention of the arcade videogame? So who was really “first”...as if it mattered if they did it independently.

    History of GIS The Foundations: 1940 to 1975 Erik Hoel Don Cooke Bill Moreland July 2013 Version 24 1 . Background • Why? – Random conversation in Matt McGrath’s office a couple years ago after reading Nick Chrisman’s book (we all knew very little about this topic) • Focus – Timeline style approach – Nothing truly historical (e.g., before computers) • Caveats – We are not historians, merely curious Esri development staff – Intended to be low-key and fun – not scholarly – Determining what is historical is quite hard … 2 . Overview • Timeline of GIS development • Key academic developments • Significant contributors and personalities • Commercial technologies • Cold War’s influence • Impact of computer technology • Esri’s role • Lots of amazing trivia 3 . Message to Our External Reviewers Your chance to influence history! Shape how young minds perceive the past! Cement your place (and your friends) in the historical record! Expunge your enemies and the wannabees! 4 . Law of the Famous “The famous are given most, if not all, of the credit, and a large number of others who also made key contributions to the success are largely ignored.” 5 . 1941 • First program-controlled computer (the Z3) was completed in Germany, architected by Konrad Zuse – The Z3 pre-dated the Harvard Mark I – Although based on relays, the Z3 was very sophisticated for its time; it utilized the binary number system and could perform floating-point arithmetic – Today, the Z3 is widely acknowledged as being the first fully functional automatic digital computer 6 . 1945 • Secret U.S. Army team led by Geodesist Floyd Hough (HOUGHTEAM) captures vast quantities of German photogrammetric equipment, geodetic, and cartographic data – Geodetic archives of the German Army hidden in secret warehouse in Saalfeld – Data included first-order geodetic surveys of large parts of Soviet Union and Eastern Europe – 90 tons of captured materials – Secured a nucleus of German geodesists – Much remained secret till 1990s 7 .

  • Oral History of Alan Kotok
    Oral History of Alan Kotok Interviewed by: Gardner Hendrie Recorded: November 15, 2004 Cambridge, Massachusetts Total Running Time: 2:36:36 CHM Reference number: X3004.2005 © 2005 Computer History Museum Q: Today we have Alan Kotok, who’s agreed to an oral history for the computer history museum, and its Oral History program. Maybe Alan, you might start off-- I think it’s always interesting to understand a little bit about sort of where you were born, and your family. Alan Kotok: Okay. Q: And the first recollections of what you thought you might want to do when you grow up whenever those occurred. Alan Kotok: Okay. I was born in Philadelphia. My family lived in Southern New Jersey. That just happened to be where my mother went to give birth. My father was in the retail hardware business, a family store. And I was always interested in tinkering around in the store with tools and various things. I got into model railroading, because they sold toy trains at Christmastime, and from sort of an early age I was always involved in setting up the Christmas displays. There’s a family legend, which I don’t personally recall, that my engineering career began at a tender age when I stuck a screwdriver into an electric outlet, and managed to put a notch in the screwdriver while I’m trying to pry it out, as well sending myself to the other side of the room. So, as I say, this is a family legend. There’s this screwdriver still around with this notch in it, but it looks like it might be appropriate age.

The first person shooter (FPS) video game genre and the competitive scene that was born out of it is an ideal case study to analyze this change over time. To understand how video games became so popular, one must examine their history: specifically, their development, impacts the games have had on society, and economic trajectories.

  • DEC: the Mistakes That Led to Its Downfall
    DEC: The mistakes that led to its downfall David T. Goodwin, Roger G. Johnson Birkbeck College, University of London [email protected] , [email protected] In 1987 Digital Equipment Corporation (DEC) was the number two computer manufacturer in the world with its founder being named the “‘most successful entrepreneur in the history of American business” by Fortune magazine. This paper looks at the later history of Digital Equipment Corporation and asks how an organisation that was so successful in 1988 could sink to become a takeover target for a PC hardware company ten years later. The management styles and company culture have been extensively described in Edgar Schein’s book “DEC is dead, long live DEC” but there is much more to the story. The technology that the company developed and the business decisions made in the development and the direction of that technology had a major bearing on the fate of the company. Many mistakes were made over the last fifteen years of the company’s existence and this paper offers a suggestion as to what those mistakes were. In this paper, extensive use is made of interviews with people involved at the time as well as material from the Ken Olsen Archives at Gordon College which contain many of the memos that Ken Olsen sent in his long career at DEC. It considers DEC as a case study set in the context of literature on business change and the impact of downsizing. It looks at DEC’s initial attempt to break into the business market for personal computers in 1983, the personalities involved and the competing products that the company developed.

  • Five Most Important Modeling and Simulation Projects, Events, And/Or
    Five important modeling and simulation projects, events, and/or technologies starting with the 1960’s to the present. The following are considered modeling and simulation technologies by decades they were developed in. This is by no means a complete list, since modeling and simulation has been practiced throughout known history. However, with the advent of the transistor based computer, modern modeling and simulation really took off. The 1960’s: Real-time Flight Simulation with Digital Computers Since man has dreamed of taking to the skies, there has been modeling and simulation involved. We can only hypothesize how Leonardo Davinci used modeling and simulation to come up with his sketches of flying machines. Since the invention of the airplane, student pilots had to familiarize themselves with the mechanics and feel of flight. In fact, the first truly synthetic flight training device was invented around 1910, where two half-sections of a barrel mounted and moved manually to represent the pitch and roll of an airplane. The prospective pilot sat in the top section of this device and was required to line up a reference bar with the horizon (Moore 2004). This device provided good control input and orientation training but still left much to be desired. In the late 20’s and early 30’s, they began including instrument flight training by linking the instrument gauges to the controls. It was about this time that Ed Link began selling his version of a pilot trainer to the Army Air Corps (Link S&T, 2009) and also the first Celestial Navigation Trainer to the Royal Air Force (RAF).
